While it may seem odd, there are not many difficulties in adapting this model to the digital world: instead of buying a book and throwing it away after forty people check it out, a library simply buys a license to circulate an ebook forty times. Functionally, it’s the same. The problem is that where previously libraries could buy any book they liked on the open market for the same price that any individual would pay, the move to digital licensing allows publishers to enforce more fine-grained “library pricing.” Now, instead of paying $10.39 on Amazon for a copy of Harry Potter and the Goblet of Fire and circulating that book until it falls apart, libraries will have to pay whatever publishers demand for the right to circulate a book a set number of times—probably a lot more than $10.39. It’s likely as well that libraries will eventually be competing with the literary equivalent of Netflix for the right to circulate ebooks. But while this new regime may force circulating libraries to cut back on the number of titles they provide, it won’t threaten their basic existence. Once publishers determine the market price to circulate a book, they will be all too happy to charge libraries that price.
